So I'm playing Super Robot Wars Alpha 2. Overall it runs well, usually between 50-60 FPS on 2 Gigs of RAM and an old Processor.

Yet it always goes low whenever certain Backgrounds start up for battles (usually spacey maps, like stars in the background or in the current lag lord, it looks like the Bermuda Triangle in the background what with planes and ships floating around, non 3-D).

I was wondering if anyone knew of a best setup for solving this, or if there was anything specific I could do.

It's slow because you Pc is slow.
Speedhcaks aren't magic options that will speed up the games without any problem.
It MAY speed up, but if you use them too much, you will get problems.
At least, did the bug disappear when you disabled speedhacks ?
